BENCH-PLANE.

Application filed January 26, 1914, Serial No. 814,479.

To all whom it may concern.

Be it known that I, THEODORE G. SELLEOK, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and use ful Improvements in Bench-Planes, of whichthe following is a specification.

This invention relates to bench-planes, and its object is to provide astructure which permits the bit to be quickly and easily removed forsharpening, without disturbing the adjusting means thereof.

The invention also has for its object to provide novel and improvedmeans for adjusting the bit.

Other objects and advantages of the invention will be pointed out in thedetailed description appearing hereinafter, and in order that the samemay be better understood, reference is had to the accompanying drawings,in which Figure 1 is a side elevation of a bench plane constructed inaccordance with the present invention; Fig. 2 is a longitudinal sectionon the line 2--2 of Fig. 4; Fig. 3 is a sectional detail showing aslightly modified form of bit; Fig. 4 is a section on the line 44 ofFig. 1; Fig. 5 is a section on the line 55 of Fig. l, and Fig. 6 is asection on the line 6-6 of Fig.4.

Referring specifically to the drawing the stock of the plane is ofconventional form, the same comprising a sole 10, side or checkpieces11, a rear hand grip 12 and a forward knob 13. The sole has a slot 14through which the bit 15 protrudes.

The bit 15 is carried by a member 16 which is pivotally mounted betweenthe side pieces 11 in a manner to be presently described. By'thuspivoting the bit carrier the same may be rotated to take the bit out ofthe slot 14 as shown by dotted lines in Fig. 1, the bit then pointingupward and being free of the side pieces, in which position it isreadily accessible for the purpose of removal. The axis of rotation ofthe bit carrier is transverse of the stock. The bit carrier 16 taperstoward the end which carries the bit 15, said end having a dovetailedtransverse groove 17 in which the bit seats and is held, the rearportion of the bit being shaped to lit in the groove.

The following clamping means for the bit 15 is provided: In the underside of the bit carrier 16 is a threaded aperture to receive PatentedGet. 19, 1915.

a screw 18. This aperture is so located that it intersects the inner endof the groove 17 thus allowing a portion of the back of the bit toextend into the aperture, at the place where the beveled side of thescrew head 19 seats, the aperture being countersunk to accommodate saidscrew head. By working the screw inward, the beveled side of the head isforced against the back of the bit, and the bit is forced forward to arigid seat in the groove. The bit can be readily removed by sliding italong the groove, after backing the screw.

Fig. 3 shows a slightly modified form of bit, its inner end having ashoulder 20 which abuts against the end of the bit carrier 16. The bitcarrier 16 is a hollow casting having side openings 21. The sides of thebit carrier are flat and parallel, and its width is such that it has asmall amount of side play between the side pieces 11. The bit carrier iscarried by a yoke, the side arms 22 of which latter seat in longitudinalgrooves 23 in the sides of the bit carrier. The connecting bar 24 of theyoke extends across and in spaced relation with the rear end of the bitcarrier, or that end which is opposite the end carrying the bit 15. Thebar 24 has, midway between its ends, an aperture in which is held anadjusting screw 25 which is threaded through a block 26 carried by thebit carrier, the latter having an aperture 27 to accommodate the innerend of the screw. The screw is held against travel in the direction ofits length by its head 27 and a collar or washer 28 located,respectively, on opposite sides of the bar 24. Thus, it will be seenthat when the screw is operated, the bit car rier is moved back andforth between the arms 22 to regulate the degree of protrusion of thebit through the slot 14.

The yoke is pivoted to the side pieces 11, which provides thehereinbefore described pivotal support for the bit carrier 16. Thepivotal connection is made by pivot screws 29 passing through the sidepieces and threaded into the arms 22 of the yoke. The heads 30 of thepivot screws are countersunk in the side pieces, and their shanks aredevoid of threads where they pass through the side pieces, which enablesthe bit carrier to be swung without causing the pivot screws to tightenup.

The block 26 seats against the rear end of the bit carrier 16 betweenoutstanding spaced ribs 31 and 32 on the latter, and it is pivoted atone end so that it may swing outward from the end of the bit carrier. The pivotal connection is made by a pin 33 passing through the block andheld at its ends in the ribs 31 and 32. The free end of the block isshaped to form a half nut, the thread 34- of which fits in the groove ofa worm 35 seating in a recess in the end of the bit carrier, and mountedon a pivot screw 36 carried by the latter. The worm carries a smallprojecting finger-piece 37 for operating the same.

- Upon turning the worm 35 in one direction, by means of thefinger-piece 37, the block 26 swings outward from the bit carrier '16,as shown by dotted lines in Fig. 1, and it is swung back toward the bitcarrier upon turning the worm in the opposite direction. This movementof the block results in giving the bit carrier a sidewise tilt to lineup the edge of the bit 15 with the slot 1 1.

In order to prevent the bit carrier 16 from rocking when the tool is inuse, a stout spring latch 38 is provided, the same being secured to thesole 10 and having its free end oilset and shaped to snap under the bar24. When the latch is in holding position, the rear end of the bitcarrier cannot swing downward, and it is prevented from swinging upwardby the bit 15 engaging the rear wall of the slot 1%. Upon disengagingthe latch from the yoke bar, the bit carrier may be swung to the dottedline position shown in Fig. 1, for the purpose stated hereinbefore.

I claim:

1. A'benclrplane comprising a stock having side-pieces, a yoke pivotallymounted between the side-pieces, a bit carrier carried by the yoke andadjustable in the direction of its length, and means for locking theyoke.

2. A bench-plane comprising a stock having side-pieces, a yoke pivotallymounted between the side-pieces, a bit carrier carried by the yoke, anadjusting screw carried by the yoke and having a threaded engagementwith the bit carrier, and means for locking the yoke.

3. A bench-plane comprising a stock having side-pieces, a yoke pivotallymounted between the side-pieces, a bit carrier having longitudinal sidegrooves, in which the yoke arms seat, means for adjusting the bitcarrier in the direction of its length, and means for locking the yoke.

4. A bench-plane comprising a stock having side-pieces, a yoke pivotallymounted between the side-pieces, a bit carrier carried by the yoke andadjustable sidev. ise and in the direction of its length, and means forlocking the yoke.

5. A bench-plane comprising a stock having side-pieces, a yoke pivotallymounted between the side-pieces, a bit carrier carried by the yoke, apivoted member carried by the bit carrier, an adjusting screw carried bythe yoke and having a threaded engagement with the pivoted member, aworm carried by the bit carrier and having a threaded engagement withthe free end. of the pivoted member, and means for locking the yoke.

6. A bench-plane comprising a stock, a bit carrier, a support for thebit carrier carried by the stock, a pivoted member carried by the bitcarrier, an adjusting screw car ried by the support and having athreaded engagement with the pivoted member, and a worm carried by thebit carrier, and having a threaded engagement with the free end of thepivoted member.

In testimonv whereof I afiix my signature in presence of two witnesses.
